There’s the transport wizard at Our Laughing Place
It’s mostly good, but there’s a bunch of short cuts that they don’t take into account. An equally good way to the Poly is to take a bus to the TTC and either walk or take the resort monorail to the Poly. During your trip, you do want to make note of how often TTC buses come to your resort. If they don’t have many or if you don’t want to wait longer, then go to the MK and pick up the resort monorail. Wilderness will be the same, bus to TTC or the park closest to your resort and change for a bus to Wilderness Lodge. What I try to do is schedule my day around my dining and try to never have to change buses, instead going to a park and then from that park to our meal and then back to a park so that we’ll be able to get back to our hotel without transfering through DTD or TTC. That second bus will cost you 20 extra minutes with a tired child.
